BUFR Primitive
the global clock tree. Each BUFR can drive the four regional clock nets in the region it is
located, and the four clock nets in the adjacent clock regions (up to three clock regions).
Unlike BUFIOs, BUFRs can drive the I/O logic and logic resources (CLB, block RAM, etc.)
in the existing and adjacent clock regions. BUFRs can be driven by clock capable pins or
local interconnect. In addition, BUFR is capable of generating divided clock outputs with
respect to the clock input. The divide values are an integer between one and eight. BUFRs
are ideal for source-synchronous applications requiring clock domain crossing or serial-to-
parallel conversion. There are two BUFRs in a typical clock region (four regional clock
networks). The center column does not have BUFRs.
BUFR is a clock-in/clock-out buffer with the capability to divide the input clock frequency.

Additional Notes on the CE Pin
When CE is asserted/deasserted, the output clock signal turns on/off. When global
set/reset (GSR) signal is High, BUFR does not toggle, even if CE is held High. The BUFR
output toggles after the GSR signal is deasserted when a clock is on the BUFR input port.
